A lead bonding structure includes: a plurality of leads extending outward from a package; and a plurality of electrode pads formed on a circuit board. The plurality of leads are soldered to the electrode pads, respectively. Each of the leads includes a lower wide portion having a width dimension greater than a width dimension of each of the electrode pads. The lower wide portion of each of the leads is soldered to the corresponding electrode pad.

Lead bonding structure

A fixing method for fixing a terminal to a conductive pattern with a brazing filler metal disposed therebetween includes: a first step of disposing the brazing filler metal on the conductive pattern; a second step of bringing the terminal into contact with the brazing filler metal; and a third step of forming a penetrating hole in the terminal by irradiating a laser beam onto the terminal. In the third step, the laser beam is irradiated onto the terminal in such a manner that the penetrating hole is filled with the brazing filler metal melted by the irradiation of the laser beam.

Fixing structure and fixing method

A method of producing a carboxymethyl-group-containing modified hyaluronic acid and/or a salt thereof includes a step of subjecting, in a water-containing solvent having a temperature of 30&#xb0; C. or less, a dissolved raw material hyaluronic acid and/or a salt thereof to a reaction with a haloacetic acid and/or a salt thereof, the water-containing solvent including water or a liquid mixture of a water-soluble organic solvent and water, a ratio of the water-soluble organic solvent in the liquid mixture being 60 v/v % or less.

Carboxymethyl-group-containing modified hyaluronic acid and/or salt thereof and/or production method for carboxymethyl-group-containing modified hyaluronic acid and/or salt thereof

A connector includes at least one contact, a ground plate formed of a metal plate of a predetermined thickness, an insulator that holds the at least one contact and the ground plate, and a metal shell that covers an outer periphery portion of the insulator, the metal shell having a window section formed facing the ground plate and having a thickness greater than the thickness of the metal plate which forms the ground plate, the ground plate having a shell fixing section formed by folding and overlapping the metal plate and located to contact the window section from inside the metal shell, a periphery of the window section of the metal shell and the shell fixing section of the ground plate being welded to each other inside the window section of the metal shell.

Connector

A connector comprises a base insulator, a plurality of elongated plate shaped contacts arranged on the base insulator, and a cover insulator arranged to hold the contacts in cooperation with the base insulator and welded to the base insulator, the base insulator is provided with a pair of openings arranged to face each other across each of holders and to intersect with the direction in which the holders are arranged.

A low-molecular-weight hyaluronic acid and/or its salt is obtained by dispersing hyaluronic acid and/or its salt in an acidic water-containing medium.

Low molecular weight hyaluronic acid and/or salt thereof, method for producing same, and cosmetic preparation and food composition containing same

Provided a method of producing a purified hyaluronic acid type which comprises adding a water-soluble organic medium to a solution which comprises a hyaluronic acid type having an average molecular weight of 400 to 100,000 and has a pH of 3 or less to obtain a suspension, and adjusting a pH of the suspension in a range of 3.5 to 8 to precipitate a purified hyaluronic acid type.

Method of purifying a low molecular weight hyaluronic acid or cationized hyaluronic acid via precipitation from aqueous solution by addition of alcohol or acetone followed by ph adjustment

A laser welding structure that is formed by joining a stranded wire (wire) of a signal line and a welding portion (conductive metal plate) by locally applying a laser beam and thereby melting and solidifying the stranded wire of the signal line and the welding portion has the following features. That is, the melting point of the stranded wire of the signal line and the melting point of the welding portion are different. The laser welding structure is obtained by applying a laser beam to one of the stranded wire of the signal line and the welding portion that has a higher melting point, i.e., to the welding portion having a higher melting point.

Wire to conductive metal plate laser welding structure

A connector which is capable of preventing spring characteristics of contacts from changing due to sucking up of solder. A plurality of contacts each include a contact portion in contact with an electrode of a card-type electronic component, a spring portion for pressing the contact portion against the electrode of the card-type electronic component, and a connection portion which is soldered to a pad on a printed substrate. The spring portion of each contact is formed with a low wettability area on an end thereof toward the connection portion, to which solder is less likely to adhere.

A conductive terminal member is disposed at a portion between an insulating base film and an insulating cover film while insulating intermediate members are disposed at other portions therebetween. In this event, the intermediate members are formed in predetermined shapes and are located so as not to overlap the terminal member. The base film and the cover film are each melt-fixed to the intermediate members so that the terminal member is fixedly held between the base member and the cover film and with the terminal memberbent to penetrate windowsin the base and cover to form contact portions

Connector easily enabling a reduction in thickness and being structurally stable
